What the UK keeps taxing after you move
Once you are non-resident under the Statutory Residence Test, the UK stops taxing your worldwide income and taxes only UK-source items. Rental profits from a UK property remain taxable through the Non-Resident Landlord Scheme, so register with form NRL1 to receive rent without tax deducted at source. If you sell UK residential property, the gain stays chargeable to UK capital gains tax and you must report and pay within 60 days of completion. Under the UK and New Zealand double tax treaty, UK private and occupational pensions are generally taxable only in New Zealand once you are resident there, provided the right treaty paperwork is in place so UK PAYE is not applied; check the position for the State Pension and any government service pension before you draw them. And if you come back to the UK within five years, the temporary non-residence rule can bring gains and certain income realised while you were away back into UK tax in the year you return.
What New Zealand taxes
New Zealand taxes its residents on worldwide income, so the move is not tax-free at the other end. Qualifying new migrants who have not been New Zealand resident in the previous ten years can benefit from a transitional resident exemption of up to around four years, but it covers passive foreign income only, not foreign employment or personal-services income, so confirm the detail with a local adviser. The UK side, from split-year treatment in your departure year to the P85 and SA109 paperwork, is worked through step by step in our moving to New Zealand guide.
